I remember the Beagle project, which was attempting to do similar things to recall way back when.

I love that they took the time to make their shitpost (kinda) work

Some great satire and comedy here. I enjoyed the curl "installation", the .exe filename...and then I read the License. Pure gold.

I love how the exe-file is just a shell script, printing random messages.

It doesn't actually spy on you though, it just says that it does

I was thinking about switching back to Windows but finally getting missing functionalities like Recall may change my mind...

I know this is satire, but a program that logs what you were doing and when is quite helpful. I have a script that fires every ten seconds and stores the current active window's metadata to a sqlite database. Other scripts log battery level, system load and free space. I use Zeitgeist to store my clipboard history and it's backed up regularly. Another script, run by Audacious (with the "song change" plugin), logs the music I'm playing.

They don't look like they need money, but they look prime for a series A. This idea has legs.

And here I was thinking someone had resurrected NeXT's issue tracking system.

Recall is not a reverse RDP capture.
